Iceland's most active volcano has started erupting, prompting the closure of the country's main international airport.

But experts say the eruption of the Grimsvotn volcano is unlikely to cause a repeat of the disturbance to European air traffic caused by another Icelandic volcano last year.

Last year, another eruption led to a major air travel chaos for days, affecting some 10 million travellers.
